San Martin San Juan began their Argentine Division 1 campaign with a narrow 0-1 home defeat to Atletico Tucuman on January 25, 2025. The match result was a disappointing start for the newly promoted side, who fought hard but were undone by a moment of quality from the visitors in a tight contest. The game was a cagey affair for the first hour, with both teams prioritizing defensive solidity. The decisive moment came in the 70th minute when Atletico Tucuman won a free-kick in a dangerous area and their star midfielder curled a superb effort into the top corner, leaving the San Martin goalkeeper with no chance. San Martin pushed for an equalizer in the final stages, creating a couple of half-chances, but they lacked the cutting edge to break down a well-organized defense. The key incident was the brilliant free-kick, a moment of individual skill that separated two evenly matched sides on the day. The defeat left San Martin empty-handed from their opening fixture, while Atletico Tucuman started the season with a valuable away win. The San Martin coach likely emphasized the positives from a disciplined defensive performance aside from one moment.
